更改Onclick函数vars的值

本文介绍了更改Onclick函数vars的值的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我在按钮上附加了onClick功能.我希望能够在页面加载时以及通过其他功能将功能var从创建"更改为更新".我已经尝试过下面的代码，但是没有运气.

I have the onClick function attached to a button. I want to be able to change the function var from 'create' to 'update' on the page load and through other functions. I have tried the code below but no luck.

<input type="button" name="save_customer" id="save_customer" value="Save" onClick="customer_crud('create')" /> var js = "customer_crud('read')"; // create a function from the "js" string var newclick = new Function(js); // clears onclick then sets click using jQuery $("#save_customer").attr('onClick', '').click(newclick)

任何想法.

已更新

简而言之，我想更改attr onClick，就像您要更改attr名称&一样.类型.

Ok in a nutshell i want to change the attr onClick like you would change the attr name & type.

<input type="button" name="save_customer" id="save_customer" value="Save" onClick="customer_crud('create')" />

到

<input type="button" name="save_customer" id="save_customer" value="Save" onClick="customer_crud('update')" />

谢谢

推荐答案

如果可能，不要使用内联处理程序.他们没有适当的范围，也依赖于高度赞赏的eval来完成工作.

Don't use inline handlers if possible. They don't get proper scope, and also rely on the highly-frowned upon eval to do their work.

相反，您可以在.js文件中执行以下操作:

Instead, in your .js file, you can just do this:

var action = 'create'; $('#save_customer').click(function() { customer_crud(action); action = 'update'; });

第一次调用处理程序时，它将执行create，然后执行update.

The first time the handler is invoked it'll do create, and then subsequently do an update.
